Richmond Gear 1304000062 Super T-10 4-Speed Transmission, GM 2.88

The Richmond Gear 1304000062 Super T-10 4-Speed Transmission is a premium heavy-duty manual transmission engineered for GM performance vehicles, classic muscle cars, street rods, and light trucks. Built as a modern evolution of the legendary Borg-Warner Super T-10, this transmission delivers exceptional strength, smooth shifting, and long-lasting durability while maintaining the classic four-speed driving experience.

Featuring a 2.88:1 first gear ratio, this transmission offers an excellent balance between acceleration and highway performance. It is an ideal choice for vehicles equipped with moderate rear axle ratios, providing strong launches while maintaining comfortable cruising characteristics.

The Super T-10 is fully synchronized in all forward gears and utilizes a constant-mesh first and reverse gear design to minimize gear clash. Heavy-duty strut-type synchronizers provide smoother gear engagement, quicker shifting, and extended service life, making this transmission suitable for both spirited street driving and competition use.

Constructed with a lightweight yet durable aluminum case, the transmission weighs approximately 70 pounds, reducing overall vehicle weight without sacrificing strength. Its side-shift linkage design and robust internal components make it a popular upgrade for Chevrolet, Pontiac, Buick, Oldsmobile, and other GM-powered performance vehicles.

Whether you’re restoring a classic muscle car or building a high-performance street machine, the Richmond Super T-10 offers proven reliability, precision shifting, and the authentic feel of a traditional American four-speed transmission.
